Heh heh.  We used to have a program on the PDP-12 (!) that used
this technique to put out two voices on one channel,
complete with the pre-built tables to speed up output.
Actually, I think it was eventually a compiler system
that took in "note files" and wrote out "play files",
and then a player program that just read the "play files"
and dumped them to the speaker.
But I think that at some point it could do it interactively
by using tables.
